SnapshotGrosvenor is the largest underground coal mine in Queensland's Bowen Basin.

The mine has been inactive since June 30, 2024, when Anglo American suspended production following an underground ignition incident on June 29, 2024.

In 2025, Anglo American continued working with the regulator on re-entry approval requirements, with initial approval granted in August and inspections confirming limited damage to critical infrastructure. Restart plans are underway, with longwall production targeted to recommence, subject to investment approval.

Before the suspension, Grosvenor’s coal products were transported via an on-site rail loading facility shared with Moranbah North and exported to steelmaking customers via the Dalrymple Bay Coal Terminal.

In August 2025, Peabody Energy notified its intention not to complete the previously agreed transaction for the remaining Steelmaking Coal business, including Grosvenor. An alternative value-accretive sale agreement is targeted for 2026.

Summary:

The sedimentary strata of Grosvenor were deposited on the tectonically stable Collinsville Shelf on the north western flank of the basin. Basalt flows that follow structures associated with the Permo-Carboniferous strike slip system partially overlie Grosvenor. The Moranbah Coal Measures range in thickness from 250–300 m and contain splits from nine coal seam groups. The target seam is the Goonyella Middle (GM) Seam.

Underground coal mining targets coal seams at various depths. Grosvenor’s target seam is the Goonyella Middle (GM) seam. The depth of cover of the GM seam across the Grosvenor site varies from 100 to 500 metres, with depth increasing toward the north-north-east of the mine plan. The thickness of the GM seam varies from four to six metres. The seam gas composition is predominantly methane (more than 95%).

The GM seam is located within the Moranbah Coal Measures, the thickness of which ranges from 250 to 300 metres in the Grosvenor area.The Moranbah Coal Measures comprise nine coal seams and their associated splits. They are, in ascending order, the Goonyella Lower, Dysart Rider, Harrow Creek Lower, GM, P, Goonyella Rider, Goonyella Upper, QB and QA seams. The Moranbah Coal Measures also contain a tuffaceous marker bed known as the P-Tuff between the GM and P seams.

Above the Moranbah Coal Measures lies the Fort Cooper Coal Measures, the base of which is the Fairhill seam. Sediments overlying the Fort Cooper Coal Measures are predominantly comprised of sandstone, claystone, basalt, gravel and clays.
